" `Be it known that L'EZRA RHODES, of `E`rie, in the cmintyof 1} rie,"and State of Ielmsylvania, have in,-

\ Xvented a newand improved `Machine for Sawing Felloes; and I do hereby declare that the'following isa full, clear, and'exaetdesoription thereo'wliich will i enable others `skilled in the art to make and use they same, `reference being had tol the accompanying draw- H ing,`ibrming part ofthisspeeification j i This invention `ljelatesito new and useful improvements in machinesibr sawing felloes, designed to prolvide a more. simple; and'effectiveunaehine than any.

nowin use.

The ,invention consists iny the combinationV of two `concavo-convexI saws with an "adjustable mandrel, and

an'oscillating` carriage, and in the arrangement ofthe Vautomatic feeding-imechanism,ias'will` be` hereinafter i `morefully described. t

Saws.

A set-screw, O, is applied to the said earriage,.to hold it at any point to which it maybe set.

The part N of the support is fixed to a vertical shaft, P, passing through the stud M, and is provided with a worm-wheel, Q, at the bottom, gearing .with a long worm, It, which is operated by a belt from the man-- i drelworking over suitable cone-pulleys. This arrangement forms the means of automatically feeding -the block past thesaws. i

The `said `mandrel maybe adj usted in a` vertical f plane so as to present the saws tothe. block for cutting the felloes with right or other angular faces.

I am aware that two concave-convex saws have been mounted upon the 'same `mandrel for the purpose" of sawing the inner and outer curvatures of felices si' multaneously, as illustrated in the' patent of Thomas Smith, September 29,1868, but this I do not claim.

`I claim as new, and desire to secure by Letters Patentf `1.- The saws D E, in combination with the adjustablemandrel and oscillating carriage, .substantially as 'described, for the purpose specified.

2. The recessed collars F, G, and H, constructed as described, and applied to the saws D E, in the manner setforth for. the purpose specified'.

3. The arrangement of the carriage KL, adjustable carriage-suppm-t M N, shaft 1 and worm-gears Q R, all operated substantially as specied.

The above specification of my invention signed by me, this 23d dayiof December, 1868.
